I agree. I had, for many years, a pair of thin not pre-curved neoprene gloves. They were not that warm & caused forearm fatigue. I now have a pair of relatively thick gloves that are seriously pre-curved. They are very warm & create minimal forearm fatigue.

A hook to hold onto the bar would be best! Like a pirate. I bet pirate hooks don't get cold.

But most pirates sail on warm seas, so their hooks wouldn't get too cold, if I can think of some cold water pirates, I'll ask them
